X Factor 2011 wannabe Kitty Brucknell brought it to the stage this evening she rocked out to Paul McCartney and Wings' track Live and Let Die. Dressed in jet black with a huge pony tail, the kooky performer played the piano as she was surrounded by fire.

Kelly Rowland raved about the performance: "Kitty you’re a bad chick. The only constructive criticism I can give you is make it look more natural sometimes. Sometimes it looks a little bit forced or stiff or something."

And Tulisa added: "Kitty that was rock! That was what we call rock. I can never find anything bad to say about you. Every week performance wise you nail it. There’s no doubt about it you are an amazing artist and performer.

"There has been a lot of negativity around your character but getting to know you a bit more backstage this week, I think your softer than people think, so let down the barrier because there is a good person in there."

Even critical Gary Barlow had no bad words, telling the 26-year-old: "Kitty I can start to see where you’re going with this and I’m in all the way.

"In fact you are the only contestant who is trying to say something through their music. You’re creative, innovative. I’m here… ready! I can’t wait for next week."

"Kitty you are a dream to work with, you are on the phone to me night and day," kitty's mentor Louis said.

He added: "Nobody works harder than you; you absolutely deliver every single week. You are talented and you deserve to be there."
